TMZ reports the nightclub hostess -- known for her alleged affair with the golf pro and for receiving a $10 million settlement in hush money -- impulsively got married to younger boyfriend Matt Hahn in Las Vegas on Sunday after another friend's wedding.

"We are really happy and feel extremely fortunate to have one another," Uchitel told Us Weekly in a statement.

The two obtained a marriage license at a court house and tied the knot at the famous Little White Chapel -- the same place where Bruce Willis married Demi Moore and Britney Spears wed childhood friend Jason Alexander. The papers were filed the next morning, according to documents obtained by TMZ.

The festivities reportedly kicked off at 11 p.m., when Uchitel, Hahn and 12 buddies danced into the chapel to Beyonce's "Single Ladies." The ceremony concluded with the song, "That's What You Get for Waking Up in Vegas," and the newlyweds were back at Uchitel's grandma's house at midnight.

Hahn, a 26-year-old businessman and former football player at Penn State, has been living with Uchitel, 36, in San Francisco for several months.

Uchitel was a wife once before in 2004, according to TheNew York Times. She wed childhood friend and Wall Street trader Steven Ehrenkranz a few years after her fiance, Andrew O'Grady, tragically died on Sept. 11. Their marriage ended after a year and four months.
